optics + analytics

Air pollution such as ozone, nitrogen dioxide, volatile organic compounds (VOCs) and fine particulates - mostly from vehicular emissions - puts a strain on the environment and affects people’s health. Real-time monitoring of air quality is important to understand the factors that influence air pollution.

Photoionisation Detection (PID) lamps manufactured by Heraeus Noblelight in Cambridge, United Kingdom, are an intrinsic part of an innovative project that is currently being carried out in and around London Heathrow airport: the Sensor Network for Air Quality (SNAQ) with 50 stations has been installed and is measuring urban air pollution caused by road and air traffic around Heathrow airport. Measurement of Volatile Organic Compounds (VOCs) using portable PID detectors is becoming an economical way to track pollution and air quality in urban environments. PID technology enables fast detection with high sensitivity. The small battery-powered sensors are lamppost-mounted and contain a number of detectors that measure six gases, VOCs and airborne particulates. The system works wirelessly – with data being transmitted to a central server via the mobile phone network.Measurement of VOCs using portable PID technology enables fast detection at parts per billion level sensitivity. Heraeus PID lamps are the industry-leaders for lifetime and spectral purity for cost-effective, reproducible analysis. Photoionisation is the term for the absorption of high energy photons by a molecule which results in ionisation of that molecule. The current created by ionisation is proportional to the concentration of the molecule, so this provides a simple method for quantitative analysis of a variety of compounds.
